PSA/ Prostate Specific Antigen

Prostate specific antigen is a substance produced almost exclusively by the prostate which plays a minor role in fertility. The vast majority is released into the ejaculate but tiny amounts are released into the blood stream and can be detected by a simple blood test. PSA tends to increase with age and age specific normal values exist. Having a normal PSA does not guarantee that prostate cancer is absent, but makes it less likely.

Abnormally high levels of PSA can be an indication of disease of the prostate. Common reasons for a high PSA level in the blood stream may include prostate cancer, benign prostatic hyperplasia (non-cancerous growth), inflammation or infection of the prostate. PSA is used as a screening or case finding test to help detect prostate cancer.

PSA is a useful tool for diagnosing and monitoring prostate diseases, but further tests are required to confirm which condition is present. Following treatment for prostate cancer, it becomes a useful marker for disease recurrence or progression.
